Château de Blois: Interior, small oratory in the chambers of Catherine de' Medici
Catherine de' Medici was Queen consort of France as the wife of King Henry II of France from 1547 to 1559 and continued to wield power during her sons' reigns.
In its present form it consists mainly of buildings undertaken in the 16th century by Louis XII and Francis I and in the 17th century by Gaston d'Orléans (1608-1660), brother of Louis XIII. The twin-aisled, arcaded Great Hall (or Salle des Etats-Généraux) built by Theobald VI (reigned 1205-1218) survives from the Gothic phase. The most impressive part of the château is the north-west wing (1515-1524), built against the medieval ramparts for Francis I. François Mansart was employed to rebuild the south-west wing (1635-1639).
